Application filed lay 5, 1924. Serial No; 711,068.

' This invention relates to improvements in Water gauge fittings, and cons sts inthe novel construction hereinafter disclosed.

An object of the invention is to provide a fitting adapted'to support a water glass, together with. illuminating means so arranged that the reflection of the light from said illuminating means will make the water glass visible, with provision for guarding the water glass to prevent dispersion of theglass particles in the event the glass is a broken.

Another object of the invention is vide a water glass fitting equipped with illuminating means for illuminating high pressure marine or stationary service=constructed from a unitary casting and designed for convenient mounting in the water line.

Additional advantages of the structure will appear from the following detailed description taken in connection with the accompanying drawing, in which Fig. 1 is a plan view of the fitting. Fig. 2 is a side elevationpartially in section. 1

.Fig. 3 is an elevation at right angles to Fig. 2.

In the embodiment of the invention illustrated in the drawing the fitting is shown as including a metallic frame substantially y a top plate 4 and a bottom plate 5. The J whole fitting thus described is preferably made from a unitary casting from which projects a casing 6. for the illuminating means. The panels 1 and 2 are in the form of an open frame having angular flanges 7 running longitudinally thereof and at the sides. The flanges. 7 constitute retaining means for transparent panes 8, thereby providing window openings through which the water glass- 9 supported within the fitting may beobserved. The angular arrangement of the panels 1 and 2 provides a structure so that natural light is admitted to the fitting, thereby equipping the fitti so that the au 'e ma be read either by nZfinal or artific i al light. y The water glass is in theform of a tube that is fitted between the plates 4 and 5.

Stuffing boxes andpipe connections 10 are mounted on each of'the end.jplates 4; and 5 to proplate within said housing.

of the water glass, thereby affording means for connecting the waterglass-with-the pipe line. The wall 3 has. a cut out portion or opening near the base-of the fitting, said opening being closed by a screened closure 11 attached to the'wall 3 adjacent to the edges of the opening by screws 12. This reticulated opening provides means of cscape for the high pressure steam in event of breaking of the water glass. I

-The wall constituting the partition between the casing 6 and the interior of the fitting is provided with a longitudinal slot 13' in parallel alinement with the water glass supported within the fitting. The longitudinal slot constitutes the only opening between the casing and the interior of the fitting and is positioned so that the light from the illuminating element is projected through the slot against the water glass rendering the water glass visible so as to determine the level of the water therein.

' The casing 6 is shown as provided with a separate top plate 14 on the'under face of which is mounted a socket 15 having an electric light'bulb 16. On the upper face of the plate 14 is a socket 17 for receiving an electric wire conduit 18, the wire within which, it will he understood, connects into having a longitudinal slit through the wall adjacent to the guard, a separate cover plate for said housing, and an illuminating element removably supported by said cover 2. A watergauge fitting comprising awater gauge guard having converging integrally united front walls adapted to removably support transparent; windows, a metallic back wall, end plates, awater gauge supported between; said end plates within the -guard, a housing integrally formed with said back wall and having a longitudinal slit through the wall adjacent to the guard,

said housing being provided with an open upper end for the insertion of an illuminating element, a separate cover plate for said housing, and an illuminating element removably supported by said cover plate within said housing.

3. A Water gauge fitting comprising a water gauge guard having converging front walls adapted to removably support transparent windows, a metallic back wall, end plates, a water gauge supported between said end plates within the guard, a housing integrally formed with said back wall and having a longitudinal slit through the wall adjacent to the guard and provided with an open upper end for the'insertion of an illuminating element, said housing extending downwardly from the upper part of said ported by the other wall of said frame, there being a longitudinal slot between the casing and the frame and an opening in said other wall below said casing, a water glass supported within the frame in longitudinal alineinent with said slot, and a screen covering said opening in said other Wall below said casing.
